FIG. 1 is a diagram illustrating a device control method according to anexemplary embodiment.

A device 100 may obtain a hovering input 10 while executing anapplication. Throughout the present disclosure, the term “application”may refer to a set of a series of computer programs for performing atask. One or more exemplary embodiments may include variousapplications. For example, applications may include a music playerapplication, a game application, a video player application, a mapapplication, a memo application, a diary application, a phone bookapplication, a broadcasting application, a fitness aid application, apayment application, and a picture folder application, etc. However,applications are not limited to these.

The device 100 may obtain a hovering input from a user. The hoveringinput indicates an input method of locating a hovering input unit 10(for example, an electronic pen or a finger) within a predetermineddistance of the device 100, changing a capacitance detected by thedevice 100, and transferring an instruction for performing an operationintended by the user to the device 100. A type of the hovering input maybe determined based on a distance between the device 100 and thehovering input unit 10 that generates the hovering input. The type ofthe hovering input may also be generated based on at least one of amoving pattern and a moving direction of the hovering input unit 10.

For example, the device 100 may determine a first hovering input havinga first depth (i.e., the distance between the device 100 and thehovering input unit 10) and a second hovering input having a seconddepth (i.e., the distance between the device 100 and the hovering inputunit 10), as different types (e.g., classes) of hovering inputs. Thedevice 100 may also determine a third hovering input (e.g., when thehovering input unit 10 moves clockwise) and a fourth hovering input(e.g., when the hovering input unit 10 moves counterclockwise), asdifferent types of hovering inputs. The device 100 may also determine afifth hovering input (e.g., when the hovering input unit 10 moves in acircular shape) and a sixth hovering input (e.g., when the hoveringinput unit 10 moves in a rectangular shape), as different types ofhovering inputs.

The device 100 may obtain metadata regarding the application beingexecuted by the device 100 at the time the hovering input is obtained.For example, the device 100 may obtain information regarding contentdisplayed by the application being executed and information regarding anobject displayed by the application. When the application is executed,the content may be multimedia including at least one of texts, images,and moving pictures that may be provided by the device 100. When theapplication is executed, the object may be an identification mark thatis output to control the application so that the user may receivedesired content, and may include an icon, etc. According to anotherexample, the metadata regarding the application may include informationregarding at least one task that may be performed when the applicationis executed, and information regarding a relationship between the atleast one task and an obtained user input, etc. For example, themetadata regarding the application may include a task that deletes aphoto when a photo storing application is executed, an identificationvalue that may identify a task that edits the photo, informationregarding a task corresponding to an obtained user hovering input, etc.

The task may include another application relating to an operation of theexecuted application or another operation that may be performed inassociation with the operation of the executed application. In thisregard, the operation may be distinguished according to a function thatmay be performed by the device 100. For example, when the video playerapplication is executed, the device 100 may perform a first operationthat performs a function to play a video, and a second operation thatperforms a function to stop playing the video, etc.

When the device 100 executes the video player application, the task mayinclude a video editing application relating to the video playerapplication. According to another example, the task may include a videostop operation that may be performed in association with an operation ofplaying a video of the video player application being executed.

A plurality of tasks may be identified according to a performing unit(e.g., multiplier) used to perform one operation relating to theoperation of the application being executed by the device 100. Anoperation performing accuracy may be determined according to theperforming unit. For example, when the user explores a specific frame inthe video player application, a unit of the explored frame may differaccording to the performing unit. For example, the device 100 mayexplore a play section in ten frame units or in one frame unit. Thiswill be described in more detail with reference to FIGS. 15 and 16later.

The device 100 according to an exemplary embodiment may obtain a userinput of various types. For example, the device 100 may obtain thehovering input. According to another example, the device 100 may obtaina touch input. The device 100 may also obtain a signal generated whenthe user clicks a button of the hovering input unit 10.

The device 100 may determine that the hovering input is not valid whenthe execution input is not obtained within a threshold time unit (e.g.,predetermined time) after obtaining the hovering input. For example, ifthe execution input is not obtained within 2 seconds after obtaining thehovering input, the device 100 may determine that the hovering input isnot valid.

The device 100 may perform the selected at least one task based on theobtained execution input. For example, when the video player applicationis executed, if the task that stops playing the video is selected, andan execution input generated by moving the hovering input unit 10 to theright is obtained, the device 100 may perform the task that stopsplaying the video. However, this is merely an example of the executioninput and the present disclosure is not limited thereto.

FIG. 4 is a diagram illustrating a method of selecting one of aplurality of tasks based on 3D location information of a hovering inputobtained by the device 100, according to an exemplary embodiment.

Referring to FIG. 4, when the device 100 executes a menu application, aplurality of objects indicating a plurality of applications that may beexecuted by the device 100 may be displayed on a screen of the device100. For convenience of description, an icon will be described below asan example of an object. However, this is merely an example and anobject may include other various types of identification marksindicating the plurality of applications in addition to an icon.

For example, an icon indicating a message application, an iconindicating a contact number application, an icon indicating a callapplication, etc., may be displayed. A user may request the device 100to execute an application indicated by an icon by selecting the icondisplayed on the device 100.

The plurality of icons displayed on the device 100 may include a unitedicon 420 indicating the plurality of applications among the plurality oficons displayed on the device 100. The user may select the united icon420 to execute at least one of the plurality of applications indicatedby the united icon 420. The user may select the united icon 420 byholding the hovering input unit 10 at a location corresponding to theunited icon 420.

The device 100 may determine whether a hovering input unit 410 a, 410 b,or 410 c, that generates the hovering input is held at the locationcorresponding to the united icon 420. In this regard, holding refers toa stop operation performed for a predetermined period of time withregard to the device 100 in which the hovering input does not contactthe device 100 within a predetermined distance range. In this regard,information regarding whether the hovering input unit 10 is held at thelocation corresponding to the united icon 420 may be determined bydetermining whether a difference between 2D location information of thehovering input unit 410 a, 410 b, or 410 c, and 2D location informationof the united icon 420 is smaller than a threshold value with respect tothe device 100. When the difference between 2D location information ofthe hovering input unit 410 a, 410 b, or 410 c, and 2D locationinformation of the united icon 420 is smaller than the threshold value,the device 100 may determine that the hovering input may be obtained atthe location corresponding to the united icon 420.

For example, when a point at which two side surfaces of the device 100cross each other is set as a reference point, and a difference betweenan x and y coordinate of the united icon 420 on a 2D plane based on thereference point and an x and y coordinate of the hovering input unit 410a, 410 b, or 410 c, based on the reference point is smaller than thethreshold value, the device 100 may determine that the hovering inputunit 410 a, 410 b, or 410 c, that generates the hovering input is heldat the location corresponding to the united icon 420.

The device 100 may select at least one of the plurality of applicationsindicating the united icon 420 according to the 3D location informationof the hovering input. In this regard, the 3D location information ofthe hovering input may be determined according to a distance between thedevice 100 and the hovering input unit 410 a, 410 b, or 410 c, at thetime the hovering input is obtained. For example, when the 3D locationinformation of the device 100 is set as 0, if the hovering input unit410 a at the time the hovering input is obtained is located at a pointhaving a distance z from the device 100, the 3D location information ofthe device 100 may be set as z.

The device 100, according to an exemplary embodiment, may selectdifferent applications when the 3D location information of the hoveringinput is different than z, e.g., z1 and z2. For example, the pluralityof applications indicated by the united icon 420 may include a photofolder application, a camera application, and a photo editingapplication. When the hovering input having z1 as the 3D locationinformation is obtained, the device 100 may select the photo folderapplication. When the hovering input having z2 as the 3D locationinformation is obtained, the device 100 may select the cameraapplication. When the hovering input having z3 as the 3D locationinformation is obtained, the device 100 may select the photo editingapplication.

As illustrated by hovering input unit 430, the executing an applicationmay be initiated by performing an operation, e.g., a gesture, at adistance from device 100. However, the present disclosure is not limitedto this.
